The remote FreeBSD host is missing one or more security-related updates.

Description

The Samba project reports :

All current released versions of Samba are vulnerable to a denial of service on an authenticated or guest connection. A malformed packet can cause the smbd server to loop the CPU performing memory allocations and preventing any further service.

A connection to a file share, or a local account is needed to exploit this problem, either authenticated or unauthenticated if guest connections are allowed.

Solution

Update the affected packages.
